Background: We have doubt about the truth that Type 2 DM is associated with chronic hepatitis C infection. The aim of our study was to prove a close relationship between chronic HCV infection and type 2 DM in korean patients. Methods: We reviewed the out-patient's medical records of 466 patients with type 2 DM who visit the Sung-ae hospital from March 2000 to August 2001. Diabetic patients were analyzed for the following variables: age, sex, waist circumference, weight, waist/hip ratio, using of self monitoring of blood glucose, method of therapy, duration of disease, experience of previous transfusion, major surgical procedure, accompanied disease, liver function tests (LFT), HbA1 c. We ruled out patients with liver cirrhosis. Results: Hepatitis C virus infection was observed more frequently in patient with Type 2 DM. Of 466 Type 2 DM patients, 13 patients were infected with Hepatitis C virus (2.79%). Compared with mean prevalence of Korean population (1.3~1.6%), it's value is very high. the other hand, 21 patients were infected with Hepatitis B virus (4.5%). Such results are similar to mean prevalence of the general public (4~5%). Conclusions: Prevalence of hepatitis C was closely associated in korean patients with type 2 DM. And an increased prevalence is independent of cirrhosis.

Sleeping is important for human being in that it has a great effect on their daily activities. considering that an average adult sleeps seven to eight hours a day, a third of our life is spent in bed. Just a sresearch on the enviorment and clotyin gin the daytime life is important, so are the studies on the sleeping environment and bedding. The presesnt study intends to make consumers aware of the important of the bedding science and help the manufacturers develop efficient, up-to-date beds. For these two purposes, consumers' recognitions and opinions on the features of the bedding they sleep in were surveyed, and also experiments were conducted to find out the thermal features of bedding required for pleasant sleeping. In the study, a questionsire consisting of various items on the fearures of bedding was designed and distributed randomly to consumers in Korea to survey the patterns in which they but, use and maintain their beddings. Their answers on each item were analyzed to find out the differences in the patterns and opinions that appears according to the age. And a comparative study of the findings was performed with the Japanses ones. The results of the sutyd are as follows. The important points tto be considered for purchasing bedding are air permeability, humidity absorption and thermal insulation. It means that the consumer regard the function of the product as important, but thermalinsulation, air permeability and heaviness cause dissatisfaction from the use of bedding. Most of subjest enjoy their sleeping life by using traditional cotton quit, but many of them hope to purchasen silk, wool and down/feather quilt, and the main sleeping life of the cosumer is of Korean style, while that of younger generation changes gradually into weatern one, showing their individuality and varety. The use of heater and air conditioner in the bedroom means the relative lowering the rate of attaching the importance to the function of bedding. And also, this study shows a similar trend towards the importance and dissatisfaction of bedding, and the perception of the bedding of younger generation between both in Korea and in Japan.

In this paper, the fabrics for Korean folk clothes(KFC) undergoes repeated laundering under given condition. After this cyclic laundering was applied, the mechanical properties of the specimen were measured using KES-F system in order to evaluated the end-use performance of fabrics for KFC. And also, the crease recovery of fabrics for KFC were measured by shirley crease recovery tester. 78 different kinds of commercial silk fabrics and polyester fabrics for KFC were used for this study. The experimental results were analysed statistically to relate the mechanical properties and the crease recovery of fabrics for KFC. Furthermore, these changes in dimensional stability, mechanical properties and handle of fabrics for KFC were discussed in comparison with those values for silk fabrics and polyester fabrics. The results obtained are as follows. 1. Regardless of materials, remarkable increase are observed in shrinkage of the fabrics for KFC about repeated laundering, but dull increase are observed in shrinkage after 10 cycles of the repeated laundering. On the other hand, slack extend are observed in dimensions after 20 cycles of the repeated laundering. The shrinkage of fabrics for KFC after 10 cycles of the lundering showed that the silk fabrics are 1.74±0.33% (warp direction) and 1.35±0.23% (weft direction) and the polyester fabrics are 1.45±0.22% (warp direction) and 1.25±0.23% (weft direction). 2. Except for tensile property, these changes in mechanical properties of fabrics for KFC by laundering have ±16 range of bending, shearing, compression, surface, thickness & weight as compared with before laundering. Particularly, the LT and RT about 1∼3 cycles of the repeated laundering showed remarkable decrease. And SMD, WC, T & W of fabrics for KFC by the laundering were more increased than one for original fabrics. But B, 2HB, G, 2HG, 2HG5 were decreased more than one for original fabrics. 3. "Stiffness", "Anti-drape", "Crispness" and "Scroop" hand values decrease and"Fullness & softness", "Flexibility & softness" hand values increase with repeated laundering. 4. Remarkable decrease are observed in crease recoveries about 1∼5 cycles of the repeated lundering, but slack decrease are observed in crease recoveries after 5 cycles of repeated laundering. The crease recovery of fabrics for KFC have negative(-) correlation with LT, RT, G, RC and MMD, This fact implies that the smaller these values, the larger the crease recovery. The crease recovery of fabrics for KFC has a high degree of correlation with the mechanical properties such as shearing, compression, surface property. And also, the crease recovery are expected by measuring the mechanical properties such as G, 2HG, 2HG5, RC, WC, LC, MIU, MMD and SMD, according to the obtained regression equation.
